Geophysical Imaging of Shallow Stratigraphy in a Groundwater Aquifer in Mississippi

(Harry & UA Colleagues Zheng, Rodriguez, and Bowling)

We are working with the Hydrogeology Research Group at UA to develop a detailed image of the shallow stratigraphy at the MADE hydrogeological test site in Mississippi. Over 100 groundwater monitoring wells are located on this site, and numerous tracer studies have been conducted. We have conducted ground penetrating radar, 2-D and 3-D seismic, electrical resistivity, and coring studies to be integrated into a sequence stratigraphic model that will be used to characterize aquifer heterogeneity. These models will be used to develop numerical simulations of groundwater flow and contaminant transport in a heterogeneous aquifer. The top image below shows the uninterpreted a) outcrop, b) GPR, c) seismic, and d) resistivity data (click on image for larger view). The lower image shows the interpreted data (click on image for larger view)
